Front Thickness Mounting Hole

The oor sensor should be installed within an approved non conductive installation pipe in accordance with EN 61386-1, which is embedded

in the oor. The pipe (exible conduit) should be placed as high as possible in the suboor. The oor sensor should be located equidistant

between two runs of the heating element with the tip at least 300mm away from the outside edge of the heater.

The enclosed 3 meter sensor cable can be extended up to 50m by means of a separate cable. The installation pipe must not contain any other

cables, such as the supplies to the heating wire. The switching peaks of such current supply lines may create interfering signals that prevent

optimum thermostat function. The heating supply cable should be placed in a separate pipe.

In the event of sensor failure, replacement of the sensor can be carried out with ease providing the sensor is installed within exible conduit.

The oor sensor should never cross the heating element.

Remove this sensor from circuit before performing any high voltage insulation tests.

IMPORTAT: ALWAYS DISCONNECT THE MAINS SUPPLY VIA THE SWITCH IN THE MAIN FUSE BOARD, CONSUMER UNIT BEFORE

COMMENCING ANY ELECTRICAL WORK. WHEN CONNECTING CABLES TO THE THERMOSTAT, ENSURE THAT ALL TERMINAL

SCREWS ARE FULLY TIGHTENED AND THAT EARTH WIRES ARE SLEEVED AND THAT NO BARE WIRES ARE SHOWING.

Release the front of the thermostat by

inserting a small at screwdriver into

the 2 slots on the base.

Make electrical connections as de-

tailed in previous section.

Electrical connections are to be made as detailed on diagram. The circuit supplying this controller must be protected by a 30mA RCD. All

electrical connections must be performed by a fully qualied and part P certied electrician. Any doubts surrounding the installation of this

controller should be passed to the distributer prior to installation. Testing of all under-oor heating systems should take place prior to oor

coverings being installed..

Mount base part of thermostat onto

either a BS recessed or surface

mounted box.
